The reinforcing Ineniber 1l extends from one i2 of the opening' 9 pastfthe other erige lll of the opening, thereby to define e yieldeble tongue l nclepted. to extend across the opening;` 9 enti 'to overlap the initial en of the reinforcing ,member il. There is an opening 16 in the tongue l5 through which the valve stern l? extends, the valve stern 17 lying `hetween the edges 12 and 14 of the opening 9 in the outer eeeing; The valve Stein 17 isveqnipped et one end With e heed 18 hearing directly against the .interior oi the inner tube 6 The valve Stern 1'?

One of the .end WallsS ,of the section e is equipped with. en outstanding rib 20 y extended entirely' across the end Wall. This rib 20 ie adapted to register in e groove 21 formed in the next adoining section7 all of the seetienebeingdup ieetee Each section 4L is equipped upon its Outer face, end ad@ jeeent one Send, vir-ith transversely extended rrihe 2% Adjneentits opposite end, each secvtion is .equipped with longitudinally en tended ribs 23, the ribs 23 and the ribs 22 covering; the entire treadfeee of each seetion tongue and the groove Construction 20-21 lvotwithstencling the eet'thet the j is one of the simplest, and in many respects, the most satisfactory means of operatlvely connecting a plurality of tire sections of the V parts not only'open and admit foreign matf terbut, at times, become disengaged from each other. In the present instance, the

weaker end of the. tire section, to wit, the Lendv which yisv provided with lthe cove 21u/1s reinforced by the .longitudinal y extended ribs- 23. That 'end' of; the section" which is reinforced by thexto'n'gue 20, does not require the reinforcement afforded by the ribs 23 and,l indeed', it is'desirable that this end of the section should yield to a slight extent in order that the tongue 20 may be engaged 'properly with the groove 2l. With this end 'in view,`the transverse ribs 22 are provided, adjacent the tongue 20; Now although thelong'itudinal ribs 23 serve to reinforce one end of the section, adjacent the' groove 21, they have no tendency to prevent relative' movement circumferentially of thel wheel, vbetween th ground, and as a consequenc,'there would bea tendency' for the outer end of the ton e 20 to be torn ed' the end wall 'of thesection, were it not for the presence'of the transverse ribs 22. Thesey transverse ribs 22 being nterposed in front of the rib' 2O serve to receive the shock dueto the-contact between -thewheel andthe ground,=as the wheel ro-v tates, and thus, a looseningo'the rib 20 is prevented.

The device hereinbefore' ldescribed is to be used with an inner tube. The invention may be applied toa single tube tire, indicated at 24 in Fig. 5. In this forin of the invention the tube 2tis devoid of the opening 9. The tire 24, however, is equipped at one end with the rib 20, and is grooved at' its other end to receive the corresponding rib 20 ot an adjoining section, as hereinbefore pointed out.` The' valve is indicated at 25, and is of the construction hereinbefore set forth.v f y ln Fig. 6`the preferred form of the in-y vention is v'shown Atogether with sundry niodiiications. VIf desired, as shown in Fig. 6 each section 26 may-be 'equipped at one end with a rectangulat rib 2'? and with a correspondingly shapedgroove 28 in its o posite end, the rib 20 and thegroo've 21 1n the preferred form oit the invention being preferably of sen1i-circular cross section. Each section 29 may be convexed throughout its entire crosshsection, as indicated at 30 to fashion the rib, the section being cone section and thel upon the riniJ caved throughout its entire cross. section as indicated at '81', to form the groove. The lsection 32 may be brought' to e. point at one '.Wth the rib 33.

In order to provide against accidents arising from a puncture of the tire, it is not necessary, in the' present invention, to carry upon thecar, a complete tire. One or more ofthe sections, in deiiated condition, are

carried within a suitable receptacle thereby econofmizing space and'dispensing with the additional weight incident to the carryingoi a.completed tire, is sometimes done. When any one section uponthe wheel becomes deflated,l the car may be rolled ahead la few feetuntil the deflated section is 'tree vfrom the ground, thereby obviating the use of a jack. The wing nut 19 may be removed from: the valve stem 17, permitting the de- ;iialed section .to be lifted olf the rim 3, anvo't vth ,wing um: 1e

p ing applied to 'the valve stem'. 17, to engage the rim 3, end to hold section beingereadily mounted in place,

- the section upon the rim.

In' placing the inner tube 6 Within the casing 5, the inner tube, being deflated, is thrust through the opening 9. The free edge'of the tongue 15-is then tucked into `the opening, to overlap 'the side wall 7 of the section 4. The section may then be placed inthe manner hereinbefore described.

The interlocking elements represented byI groove 21 serve not only to prevent the sections from having indeA` the rib 20 and the pendent relative movement, transversely of the rim, reinforcing element Vat the end of each section Atendingto'prevent an undue flattening of tlie sections. -.The reinforcing strip-11 servcs'to protect the inner tube 6, andthe tongue 15, formed by the free edgev of the or completed wheel, as

but, as well, each rib' 2O serves as a.

reinforcing strip serves to' prevent the inner'l' tube 6 from coming into contact with the rim 3. Owing to the fact that certain of the ribs 22 extend transversely of each section 4, and owing to the furtherv fact that other of the ribs 23 extend longitudinally of each section, the wheel will e. prevented from slipping either transversely or longitudinall is claimed is;I s A tire com rising a plu-ralityof individually removab a, groove in one end wallandlf'bein'g p ovided upon its other end wall with a'y tongue adapte to register in the groove oi.
